Applicatioa "law 9, 3.5518. serial We. FQdloitk To @251 whom may concernBe it known that L citizen of the United States, residing at New York.WW, county of New York,

' .l orlr, have invented an improvement otlpacisg Attachments i Marzines of which the following is a specie Mus invention has for itsobject to produce line spacing attachment which shall be supplemental tothe regular line spacing device of a writing machine and be applied tonew or old machines and which will. the operator to give to the linesany required uniform spacing, to space irregularly or to re-aline withperfect accuracy a sheet that has been removed.

It is of course Well understood that in Writing machines as ordinarilyconstructed the spacing of the lines is effected by the engagement of apawl Wllil'hillle teeth of a ratchet wheel, three spacings beingordinarily provided which are known as single, double and triple spaces.My novel attachment is supplemental to this ordinary spacing devicewhich may be used in'lieu of the attachment if preferred; Should it berequired to space'irregularly, however as in filling in blanks, orshould a spacing be required other than the three arbitrary spacin srovidedby the spacing device of the machine or should it be desired toapproximately fill a sheet of limited size with a certai 'i' number oilines which would not correspond with either of the three arbitraryspacings provided by the machine it would be necessary to throw oil thespacing attachline by guesswork by and frequently to laten; that is, todraw the paper while olding the platen stationary. These diiiicultiesare wholly overcome by the use of my novel spacing attachment in whichthe forward the platen is reflected by the action of an oscillatorycollar and grip ping roller, the action of the collar hein adjustable soas to causethe roller to grig the platen at the required instant toproduce the required line space by actuation of the usual spacingdevice'of the machine.

"With the above stated and other objects in view I have devised thenovel attachinent which 1' will. now describe referring to theaccompanying drawing forming a part of rotstion of the vplaten,

it should. be uhderstood that the invention is equally applicable to anyof the various types and makes of ,writing machines in general use,certain parts only requiring; to be changed. and the principle being thesame in all cases. I

20 denotes the platen and 21 spacing. ratchet wheel which is detacha'oiysecured to the right end thereof. The platen is ordinarily shouldered,ahd the spacing ratchet wheel forms with the shoulder a groove 22 whichreceives the oscillatory collar of my novel attachment, as will be morefully explained.

The ordinary spacing mechanism comprises essentially a line space lever23, a hell crank. lever 24 and a spacing pawl 25 piw oted to the bellcrank lever and engaging the spacing ratchet wheel. The spacing somuchfor rotating the P 52, lool ing Fig. 10 an ratchet wheel is normallyengaged also by a roller 2? carried by a spring arm 27 which is rigidlysecured to a fixed portion of the machine. This roller by engagementwith the teeth of the ratchet wheel retains the platen in any positionin which it may be placed. The roller is thrown out of engagement withthe ratchet wheel by means of a lever 28. The various intermediate partsare not shown, and this mechanism is not illustrated or described indetail, as it forms no portion of the present invention and moreoverdiffers in the various machines in general use.

My novel attachment comprises an oscillatory collar 29 mounted on theend of the platen, in the present i stance in groove 22, and having anenlargement provided with an elongated socket; 30 to receive a grippingroller 31. It will be noted that the lower portion of the socket is ofless width than the diameter of the roller while the upper end or" thesocket is of greater width than the diameter of the roller. A. lever 32pivoted in the enlargement is provided in order to lift the roller outof. engagement with the platen when it is desired to move the platenbackward, or to entirely release it, as indicatcd by the full line inFig. 3, or to use the ordinary spacing mechanism. The dotted position ofthe roller in Fig. 3 is its normal position. When the collar is in theposition shown in Fig. 3 with. the roller in the dotted position.torward movement of the collar c. upward movement from right, towardleft) will cause the roller to wedgcbctwcen the wall of the recess andthe platen and will carry the platen forward. The instant backwardmovement of the collar begins the collar will move downward away fromthe roller leaving the roller in the wider upper portion of the recessso that this backward or downward movement of the collar will. be free,leaving the platen in the position to which it has been carried by theit'orward movement. The oscillations of the collar are effected by meansof an adjustable reciprocating link 33 which is pivoted to hell cranklever 24 and to an arm 34 extending from the oscillaposition of theroller tory collar. In the form illustrated in Figs.

the hnk C-UIHPHSQSW 3, 5 and 7 to 11, inclusive, a tubular member 35, atoothed slide 36 and a scroll wheel 37 provided with a finger piece 38.The scroll wheel is mounted to oscillate on a stud 39 and is retained inplace. by a nut 40. The scroll 41 on the scroll wheel engages the teeth42 on the slide and causes the slide to reciprocate within the tubularmember to lengthen or shorten the link and cause more or less forwardmovement of the collar, and consequently a greater or less space betweenthe lines printed by the machine. I have shown the tubular member asprovided with a slot 43 at one end of which is a projection 4a. The

toothed slide is provided with a projection 4-5 which extends throughthe slot shown in Figs. 8 and 5. A scale 4-6 may be provided on oppositesides of the slot so graduated that the space between projections 4.4and 4-5 will correctly indicate the space between lines printed by themachine. In liigs, 3 and 5, the link is shown as short-- cncd to theextreme of its movement, which would produce the longest space withinthe capacity of the attachn'ient. The space is shortened by lengtheningthe link, which is effected by rotation of the scroll wheel to move thetoothed slide outward. a means for limiting the forward movement of thecollar, I provide a lug 4t? thereon which at the extreme of the forwardmovement of the collar will engage a suitable stop, as the hub 48carried by spring arm 27 on which roller 26 rotates.

In Fig. 6, l: have illustrated, the application of the invcntimi to aRemington writing machine. The oscillatory collar is provided with anarm t9, the spacing pawl 50 is pivoted to a reciprocating bar 51 and theadjust able link 52 is pivoted to the upper end of the spacing pawl andto arm 9. The space between lines printed by the machine is shortened byshortening the link and is lengthened by lengthening the link. The linkin this form comprises a screw 58 pivoted to arm 49, a screw 54 pivotedto spacing pawl 50, a nut 55 engaging both screws and a lock nut 56 toretain the nut in. position after adjustment. A pin 59, projecting" froma. fixed portion of the machine, is provided for engagement by lug); 4?on the collar to limit the forward movement of the collar. The socket inthe enlargement; of the collar is closed on opposite sides by coverplates operative position, as in fultline I when it is not desired touse the attachment, I provide one of the cover plates with a projection553 which may be made by indenting the metal of the cover plat e. seeFig. 6,which shows the indentation on the outer side of the cover platewhich forms the-projection on the inner side. In throwing the roller tothe inoperative position, lever 32 is swung past the projection whichacts to retain it in that position, and to rctainthe roller out ofengagement with the platen.

The operation is as follows: If the attachment has been in use and itdesired to use the ordinary spacing device of the machine, the ,gpippingroller is thrown out of engagement with the platen, as in Fig. 3, andthe link is adjusted to its longest length and spacing pawl 25 is turnedinto operative position as in dotted lines in Fig. l. The condition ofthe machine is then precisely the same as it theattachment had not beenapplied. Suppose now that it is desired to use the attachment. Spacingpawl 25 is as clearly In order to lock ri i iin'r roller 31 out of, s lt. a s in big. 3.

thrown out of operative position as in full lines in Fig. and lever ismoved to the clotted position in l ig. 3 which permits the grippingroller to drop down into operative position. The space hetween the linesprinted by the machine determined by the length of the link which isadjusted to the requirements of use and will produce anyreqiiiiredspacing within the capacity of the machine. if it is requiredto print a line and then. to space regnilarly from that line, ili'cpaper is -ilaccd in position to print that line and then spacing by theattaclnneat will proceed from that line as already described.
